• A short-term frequency support strategy for wind power integration is proposed. • Independent wind turbine provides spontaneous support based on its own kinetic energy. • Coordinated wind turbines implement corrections based on centralized dispatching. • This strategy improves grid frequency performance under communication constraints. When a frequency event causes a significant drop in grid frequency, wind turbines (WTs) can provide short-term frequency support (STFS) by releasing their rotor kinetic energy. However, due to the wide-area distribution of the grid and the limitations in communication cost and reliability, there are certain difficulties in implementing the STFS strategies that rely on real-time communication to collect rotor speed information of WTs. This paper proposes an STFS strategy for grid-wide wind power integration via the comprehensive utilization of independent and coordinated resources. First, a unified form of STFS for WTs is designed based on a power-frequency function, which is derived from the optimal frequency trajectory defined by the power-time function. Then, the STFS strategy, parameter setting, and implementation for grid-wide wind power integration are proposed, which involves independent STFS WTs providing spontaneous support and coordinated STFS WTs implementing harmonized correction, aiming to optimize critical frequency dynamic indices under constraints of wide-area communication. Finally, the effectiveness of the proposed method is validated using an IEEE 39-bus system with five aggregated wind farms.
